I have the same problem after installing 14.2.760, and updating to 14.2.770
the data for the Administrator%20Daily%20Summary%20Report_Sep%2010_%202018%206-00-39%20PM%20340.html has expandable sections, and if you open the html file with notepad, you can see the individual lines. the expansion indicator changes state when I click it, but the data is not displayed.
